(Cl. 126-270) My invention has for itsobject improvements in sunoperated devices in order to make use of solarheat, as, for instance, for cooking purposes.

According to my invention, my improved solar heating device includes areflector comprising, for instance, a parabolic mirror and a carrier forthe material to be heated, the reflector being mounted on an arrangementthat is shiftable with reference to said support, whereby the zone ofconcentration of the solar rays may always be shifted by the reflectorWithin the limits of the area carrying the material to be heated.

The reflector may be mounted on a system of levers which provide for ashifting of the reflector with reference to the carrier of the part tobe heated, the refiector and the carrier being pivotally secured to acommon supporting spindle.

The carrier of the material to be heated is preferably shiftable withreference to the zone of concentration of the solar rays so as to allowadjustment of the heating through movement of the material to be heatedwithin this concentration zone.

The reflector may also comprise a series of sectors. The sectors of thereflector may be secured together through a fastening of the tips of thesectors as provided through a central flange.

These sectors may also be pivotally secured to a spindle so that theymay expand to form the reflector or be folded into inoperative position.

The sectors may furthermore include means for moving one sector byengagement with another whereby said sectors may open after the mannerof a fan.

I will now describe with further detail a preferred embodiment of myinvention, reference being made to particular embodiments thereof givenby way of example and illustrated in accompanying drawings in which:

Fig. 1 is a side view of an arrangement according to my invention.

Fig. 2 is a sectional view taken along line 22 of Fig. 1.

Fig. 3 is a bottom view illustrating the arrangement for securing thesectors forming the reflector.

Fig. 4 is a cross-section taken along the lines 4-4 of Fig. 3 and viewedin the direction of the arrows.

Fig. 1 is a partly sectional view of a heating device carried on a stand14 inside which pivots the lower vertical end of a bent rod 15 carryingat its upper end means for supporting the part or material that is to beheated.

The mirror comprises a series of parabolic elements or sectors 16secured to a central flange member 17. Said central member is pivotallysecured to a connecting rod 18 that is in its turn pivotally secured at19 to the bent rod 15. A control handle 20 for the mirror is rigid withthe central flange member 17. This handle includes a stud 20' whichslides in a space 21 provided between two sections 22 and 23 forming theupper end of the rod 15, as will be seen in Fig. 2.

States Patent The mirror returns the reflected sun rays onto the part tobe heated on which they are thus concentrated, whatever may be themovements of the mirror under the control of the handle 20 and theconsequent pivotal movement thereof with reference to the stand 14. Foradjusting the intensity of heating, the carrier 24 for the part ormaterial to be heated is pivotally secured through means including adeformable link motion constituted by the upper end 25 of the bent rod15, a member 26 rigid with the actual carrier 24 and two parallel arms27 and 28.

A system of pivotally secured arms 29 and 30 that is controlled by ascrew-operated device 31 provides for the desired shifting of thecarrier 24.

Fig. 3 shows a bottom view of the arrangement carrying the sectors ofthe mirror. This arrangement includes a flange 48 on which the arms 49may rotate coaxially round the axis 50 of a screw. A Winged nut 51engaging said screw allows locking the arms 49 in position.

Each arm is rigid with a sector 52 of the mirror and each sector isconstituted by a parabolic element and a flange 53 secured to an arm 49.This arrangement allows folding the sectors 52 over one another fanwiseas shown in the cross-section of Fig. 4.

In order to further the opening of the fan-shape arrangement of sectors,one of the arms 49 may carry along with it the following armautomatically, for instance through the agency of a flange 54 bearingagainst a portion of the following arm 49.

The manner in which the sections are bolted together may be alsoaccomplished by any other suitable arrangement, as, for example, thearrangement shown in U. S. Patent No. 2,513,961.

Obviously my invention is by no means limited to the embodimentsdescribed hereinabove, which embodiments may include detailmodifications without unduly widening thereby the scope of theinvention.

What I claim is:

1. Heating apparatus comprising, in combination, a base; a post having alower end portion mounted on said base for turning movement about avertical axis, said post extending upwardly from said base; supportmeans mounted on said post for supporting an article to be heated; and aparabolic mirror pivotally supported only by said post for turningmovement about a horizontal axis, said mirror being formed with a cutaway portion through which said post extends and being formed from aplurality of sector-shaped segments each extending from the center ofthe mirror to the outer periphery thereof.

2. Heating apparatus comprising, in combination, a base; a single postmounted on said base and extending upwardly therefrom; support meansmounted on said post for supporting an article to be heated; and a parabolic mirror pivotally supported only by said post for turning movementabout a horizontal axis, said parabolic mirror being made up of aplurality of sector-shaped segments each extending from the center ofthe mirror to the outer pariphery thereof and said mirror being formedwith a cut-out through which said post extends.

3. Heating apparatus comprising, in combination, a base; a post having alower end portion mounted on said base for turning movement about avertical axis, said post extending upwardly from said base; supportmeans mounted on said post for supporting an article to be heated; and aparabolic'mirror pivotally supported only by said post for turningmovement about a horizontal axis, said parabolic mirror being made up ofa plurality of sector-shaped segments each extending from the center ofthe mirror to the outer periphery thereof and said mirror being formedwith a cut-out through which said post extends.

4. Heating apparatus comprising, in combination, a

base; a crank-shaped post having tWo arms and having a lower end portionmounted on said base for turning movement about a vertical axis, saidpost extending upwardly from said base; support means mounted directlyon said post for supporting an article to be heated; and a parabolicmirror pivotally supported only by said post for turning movement withrespect to said support means about a horizontal axis locatedapproximately at the intersection of said arms, said parabolic mirrorbeing made up of a plurality of sector-shaped segments each extendingfrom the center of the mirror to the outer periphery thereof.

5. Heating apparatus comprising, in. combination, a base; an elongatedpost extending upwardly from said base and being mounted thereon forturning movement about a vertical axis; a carrier, for carrying anarticle to be heated, mounted only and directly on said post; and areflector independent of said carrier and being mounted on said post forturning movement with respect to said carrier about a horizontal axis,said reflector comprising a plurality of sector-shaped segments eachextending from the center of said reflector to the outer extremitythereof and being slidable with respect to each other about the centerof said reflector so that the latter may be collapsed when the heatingapparatus is not in use.

6. A heating apparatus as defined in claim and wherein said carrier hasa flat horizontal supporting surface to support an article to be heatedin a horizontal position.
